[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: A chip removal device for a CNC machine tool includes a machine tool body 1. A storage box 2 is fixedly connected to the bottom left side of the machine tool body 1, and a dust collection component 3 is fixedly connected to the rear side of the top of the storage box 2. A conveying component 4 is fixedly connected to the bottom inside the machine tool body 1 and is connected to the storage box 2. The conveying component 4 includes a square cylinder 401. A rotating rod 402 is rotatably connected inside the square cylinder 401, and a collection hopper 403 is fixedly connected to the top of the square cylinder 401. A spiral blade 404 is fixedly connected to the surface of the rotating rod 402, and a rotating motor 405 is fixedly connected to the right side of the rotating rod 402. A square tube 406 is fixedly connected to the left side of the square cylinder 401, and the other end of the square tube 406 extends into the interior of the storage box 2.

[0020] In this embodiment: the fan 303 draws air out of the housing 301 to create negative pressure, causing fine debris inside the machine tool body 1 to flow into the housing 301 through the suction pipe 302 under suction, preventing it from scattering and polluting the environment. When the fan 303 stops running, the electric valve 305 is activated to smoothly discharge the debris into the storage tank 2, achieving centralized collection of debris for subsequent processing and improving the ease of use of the dust collection component 3. Then, under the action of the collection hopper 403, the collection range can be increased and the debris can be guided smoothly into the square cylinder 401, completing the precise collection of larger debris. At the same time, the rotating motor 405 drives the rotating rod 402 to rotate, driving the spiral blades 404 to rotate, which can smoothly flow the debris in the square cylinder 401 along the spiral blades 404. With the help of the conveying channel formed by the square pipe 406 and the storage tank 2, the debris is smoothly conveyed to the storage tank 2 through the square pipe 406 for storage, achieving rapid cleaning of debris and improving the ease of use of the device.

[0021] Specifically, such as Figure 5 As shown, the dust collection assembly 3 includes a housing 301. A dust collection pipe 302 is fixedly connected to the right side of the top of the housing 301, and a fan 303 is fixedly connected to the bottom of the left side of the housing 301. The side of the dust collection pipe 302 away from the housing 301 extends into the interior of the machine tool body 1 and is fixedly connected to a dust collection plate 304. The dust collection plate 304 is fixedly connected to the top of the inner wall of the machine tool body 1. An electric valve 305 is fixedly connected to the bottom of the housing 301, and the other end of the electric valve 305 extends into the interior of the storage box 2.

[0022] Specifically, such as Figure 5 As shown, a triangular filter frame 5 is fixedly connected to the bottom left side of the inner wall of the housing 301, and the air intake end of the fan 303 is located inside the triangular filter frame 5.

[0023] Specifically, such as Figure 3 As shown, a mounting hole 6 for use with an electric valve 305 is provided on the rear side of the top of the storage box 2, and the surface of the electric valve 305 is in contact with the inner wall of the mounting hole 6.

[0024] In this embodiment: the electric valve 305 is used in conjunction with the mounting hole 6 to tightly connect the electric valve 305 with the storage box 2, forming a debris conveying channel. When the fan 303 stops running, the electric valve 305 is activated to smoothly discharge the debris into the storage box 2, completing the centralized collection of debris for subsequent processing. Combined with the blocking structure formed by the triangular filter frame 5, it can effectively prevent debris from entering the fan 303, avoid damage to the fan 303, ensure the normal operation of the dust collection component 3, and improve the ease of use of the dust collection component 3.

[0025] Specifically, such as Figure 3 , Figure 4As shown, a baffle plate 7 is fixedly connected to the top of the inside of the collecting hopper 403, and the inside of the baffle plate 7 is provided with several leakage holes 8.

[0026] Specifically, such as Figure 3 As shown, the top of the storage box 2 is provided with a connection hole 9 for use with the square tube 406, and the surface of the square tube 406 is in contact with the inner wall of the connection hole 9.

[0027] In this embodiment: the square tube 406 and the connecting hole 9 are used together to tightly connect the square tube 406 and the storage box 2 to form a stable chip conveying channel, which facilitates the discharge of larger chips. At the same time, the baffle plate 7 and the leakage hole 8 are used together to prevent large objects such as workpieces from falling into the conveying assembly 4 and avoid damage to the spiral blade 404 due to collision. It can also perform preliminary screening of chips, ensure the stable operation of the conveying assembly 4, and improve the convenience of using the conveying assembly 4.

[0028] Specifically, such as Figure 3 As shown, T-shaped sliders 10 are movably connected to both sides of the inner wall of the storage box 2, and a storage box 11 is fixedly connected between the opposite sides of the two T-shaped sliders 10.

[0029] Specifically, such as Figure 1 , Figure 2 As shown, a controller 12 is fixedly connected to the right side of the front of the machine tool body 1, and the controller 12 is electrically connected to the machine tool body 1, the dust collection component 3, and the conveying component 4.

[0030] In this embodiment: Through the function of the controller 12, the operating parameters of the device can be set according to the actual situation. It can not only generate suction through the fan 303 to complete the collection of fine debris, but also transport larger particles of debris received by the collection hopper 403 through the spiral blades 404. The two work together to complete the rapid cleaning of debris. At the same time, through the cooperation of the T-shaped slider 10 and the storage box 11, the collected debris can be received in real time, and the storage box 11 can be easily pulled out for cleaning at any time, ensuring the normal operation of the chip removal operation and improving the convenience of using the device.

[0031] Working Principle: When machining workpieces on a CNC machine tool, the operator first completes the equipment's self-check and sets the operating parameters through the controller 12. During machining, the fan 303 is started to extract air from the housing 301, creating a stable negative pressure. Under the suction, fine debris and dust inside the machine tool are sucked into the housing 301 through the dust collection plate 304 and the dust collection pipe 302. Simultaneously, the triangular filter frame 5 filters debris, preventing it from entering the fan 303 and ensuring its normal operation. When the fine debris accumulates to a certain amount in the housing 301, the controller 12 stops the fan 303 and activates the electric valve 305, allowing the debris to fall smoothly into the storage box 11 inside the storage box 2 through the channel formed by the mounting hole 6 and the electric valve 305, completing centralized collection. Larger debris falls into the baffle plate 7 under gravity, preventing material leakage. The hole 8 not only prevents large objects such as workpieces from falling into the square cylinder 401 and avoids damage to the spiral blades 404 due to collision, but also performs preliminary screening of the debris, allowing suitable debris to flow smoothly into the square cylinder 401 under the guidance of the collecting hopper 403, thus completing the collection of larger debris. Then, the rotating motor 405 is started to drive the rotating rod 402 to rotate, which drives the spiral blades 404 on the surface to rotate synchronously. Through the spiral thrust, the debris in the square cylinder 401 is pushed in a direction to the square tube 406. With the help of the conveying channel formed by the square tube 406 and the storage box 2, the debris is smoothly conveyed to the storage box 2 through the square tube 406 for storage, realizing the rapid cleaning of debris. When the processing is completed, the controller 12 stops the fan 303 and the rotating motor 405, and the storage box 11 is pulled out for debris cleaning. After cleaning, the storage box 11 is reset to restore the chip removal function of the equipment.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
